thanks pionex. im waiting to see your results. is there a possibility you take pictures of your SX wings? maybe measures? the thing is that it is imposible to find decent photo of SX wings. Magnum wings i managed to find, but SX wings, no go. just today i received an email from Austrian Hobie distributor (maletschek co). they have hobie 18 sx wings. new. €2500 - WITHOUT TRAMP!!!!!!!!!!!!!. That is roughly $3000. i could not believe my eyes. i can get 2 complete sets of sails for that money. no way im goin to buy new ones. im building it on my own, even if i have to design it myself. and again, i will make sure to post ALL MY FINDINGS ON THIS FORUM. videos, pictures, measures. and it is a promise

Hi This is MartyBoth 6160 or 6063 can be bent with out annealing if you have the right bender.180 deg bends can be bought from SHARPEPROCUCTS.COM for about $30.00 each if you can not bend your own. You can buy 6160 2 inch tubing or 6063 2-3/8 tubing witch is pipe. If any one can give me a drawing of the wings, I have the software to stress analize for both materials. As far as end fittings, I am going to machine them out of billet alu.Marty mwbeech@hotmail.com

Just a suggestion : for end fittings or for any kind of "joining" two tubes think about using Ertalon or Ertalene. These are sold as plastic/nylon blocs than can be shaped quite easely in any form : a good alternative to the Zamac fittings.I wish you succes with the projects !Michel
